"The Nikon D5200 is a solid performer that offers an impressive array of specifications for a camera of its class. Indeed, the number of features it shares with its higher-end Nikon stablemates is to be applauded. In addition to an excellent 24MP sensor that gives up precious little to that of the (non-AA filtered) D7100, the D5200 boasts a 39 point AF system, lens-dependent Auto ISO implementation and class-leading high ISO noise performance.
The D5200 stands out as the only recent-model Nikon DSLR to sport an articulated screen which comes in handy for both stills and video shooters, though we can't help but wish it was touch enabled as is the one on the Canon EOS T5i/700D. The D5200 offers a reasonable number of external controls, but as you'd expect on a camera of this class, more advanced users will have to satisfy their needs with visits to the main menu. You do have a customizeable Fn button though, and the camera's '[i]' button allows more direct access to 14 separate camera and shooting settings. If we nitpick, we'd like to see even faster access that omits a second confirmation click before you can actually change a setting in this manner. Overall though, we find that the D5200 strikes a nice balance between providing essential shooting controls without overwhelming novice DSLR users."
Just in time for the Christmas rush, the D5200 with its distinguished looks, inheritance of the D7000 series AF module, a vari-angle monitor and full HD video will probably sell like hot cakes. For the time being there's no information about US pricing or availability.
